According to legend, there are three thousand realms in the world. The so-called three thousand is just an approximate number. There are endless realms large and small. The one that encompasses the realms is called the realm sea, which is also the so-called chaos and grand mist. The boundary sea has a boundary source, yin and yang intersect, and there is no distinction between pure and turbid. Endless years ago, the Heavenly Dao gave birth to Pangu, who was born in the source of the world, and created the original world. This realm was divided into three parts, and the Heavenly Dao was also divided into three parts. The most basic level is the human world. Above the human world, there are two realms, one is the demon world and the other is the heaven. An ancient war shattered the endless continents of the human world into the void and turned into endless stars. The three realms were separated and the war was temporarily extinguished. After a long time passed, the young man entangled by cause and effect was forced to face this catastrophe. The demon blood in his body was boiling, and the human part drove him to move towards the way of a knight!
